Intro to Underscore.js

hi_underscore.js

var woot = woot || {};
woot.log = function(key) {
    console.log(key);
}

// mimics Collection.each
// http://underscorejs.org/#each
// args:
// _.each(list, iteratee, [context])
_.each(['Aldrin', 'Armstrong', 'Grissom', 'Hadfield'], woot.log);

// make a super string using Template (same syntax as ERB)

// 1. Create a data object...
// ...or use one from an Ajax call?
var data = {
    name: 'Tom',
    hobby: 'learning JS',
    beer: '3 Floyds'
};

// 2. Build a template
// call it superString
// check out that <%= variable_name %>
var superString = _.template("<%= name %> really enjoys a <%= beer %> while <%= hobby %>");
console.log(superString);

// 3. Super string is now a template function. It accepts one argument: a data object with keys that correspond to the <%= variable_name %>
var compiledTemplate = superString(data);


// 4. Log the template
console.log(compiledTemplate);
